Specific implementation mode
It summarizes
It is described below be between multiple positions (for example, region) migrate virtual desktop (for example, cloud desktop and/ Or another type of virtual desktop) to improve technology and the solution of performance (for example, reduce network delay, increase bandwidth etc.) Scheme.For example, based on geographical location or network delay by the cloud desktop example of user from a zone migration to another region It is capable of providing more satisfactory user experience, because cloud desktop can become sensitiveer.As used herein, term " user equipment " is to refer to any kind of computing device of trustship cloud desktop session (for example, server computer, desk-top meter Calculation machine, laptop computer, tablet computer, mobile phone or another type of computing device).
Cloud desktop can be run on the server in cloud.For example, cloud desktop example can be run on cloud, medium cloud table Face session capture user interaction on a user device is simultaneously real in the desktop run at different location on cloud by these interactive applications In example.But this interaction may to network delay, bandwidth, shake (for example, variation in network packet round trip time) and/ Or other performance measurements are very sensitive.If there are high latency, users may experience user equipment and show for the session of cloud desktop Lag on device or zigzag movement.Network delay often increases with the geographic distance between server in user equipment and cloud Greatly.It, can be by the server component of cloud desktop from the zone migration to user equipment presentation high latency in order to reduce network delay To the region presented to user equipment compared with low latency.In any example below, term " data center " and " region " can be with It is used interchangeably.Data center can refer to the physical location of the server component of trustship cloud desktop.Each data center can be with In a region.But one-one relationship between data center and region not necessarily.For example, region can hold Set more than one data center.Geographic area can refer to the regional extent for including the distance for starting from user equipment.Geographic area Can also refer to wherein user may where and/or may the city at hosted data center, county, location name or any other refer to Generation.
In a particular embodiment, network delay that can be based on user calculating equipment to current region and user, which calculate, to be set Standby at least one of the geographical location relative to current region is come it is determined that cloud desktop is migrated from current region.The cloud table Face can calculate in the destination region of migration based on user calculating equipment to the network delay in the destination region and user At least one of the geographical location of equipment relative to the destination region identifies.The cloud table that can will be run at current region First example in face is closed, and can be by the book of the cloud desktop of the user data comprising the user-association with the cloud desktop Destination region is moved on to from current region.It is then possible to using by the cloud desktop at mobile data volume initialization destination region The second example.When receiving user's connection request, second of the cloud desktop at the region of destination can be directed the user to Example.
In another embodiment, a kind of computing environment can be provided for migrating cloud desktop between data center. The computing environment may include the control plane layer for the book and one or more data centers for tracking cloud desktop, include cloud desktop With the current data center, one or more candidate data centers and management assembly of book.The management assembly can be used for Based on user calculating equipment to the network delay at current data center and the user calculating equipment relative to current data center At least one of geographical location come it is determined that by cloud desktop from current data Center shift, and calculated and set based on user The geographical location of the network delay at destination data center and user calculating equipment relative to the destination data center to the utmost At least one of identify one in the candidate data center for migrating cloud desktop.Can by the book of cloud desktop from Current data center moves on to identified candidate data center.Then, when receiving user's connection request, user can be determined To the second example of the cloud desktop at the candidate data center identified.
In another embodiment, it may be determined that cloud desktop should be migrated from current region.It can identify cloud table The destination region that face moves to.The book of cloud desktop can be copied to destination region from current region, while synchronously Safeguard the book at current region and the book at the region of destination.When replicating completion, can freeze at current region Knot and the associated active user's session of the cloud desktop, and the current storage of active user's session and processor state are copied to Destination region.It is then possible to be started using the book and current storage and processor state at the region of destination Second cloud desktop example, and active user's session can be reconnected to the second cloud desktop example.
Thus, it is possible to cloud desktop be moved on to another region, to improve the performance of the cloud desktop.It is also acknowledged that can For the reason of improve other than cloud desktop performance and cloud desktop is moved on to another region.For example, disaster recovery can be used as Cloud desktop is moved on to another region by a part for process.If there is the outage (or in expected data of data center Heart outage), then it can in advance or reactively move cloud desktop.As a result, user without know their cloud desktop by It is moved in data center's outage.Unique situation of the situation and non-migrating cloud desktop that are mentioned above, and be also possible to There are other situations to migrate cloud desktop.For example, server maintenance may need to migrate cloud desktop.
Cloud desktop
Fig. 1 is the computing system schematic diagram of cloud desktop environment 100.User can be for example, by running on user equipment 140 Cloud desktop client start cloud desktop session using 142.Cloud desktop client can connect user equipment 140 using 142 It is connected to the cloud desktop example 112 run on the server 110 at a region.Cloud desktop client can emulate behaviour using 142 Make the appearance of system environments, so that it looks like user equipment 140 just in 140 local runtime cloud of user equipment for user Desktop example 112.User equipment 140 can also include health monitor 144.Health monitor 144 monitor user equipment 40 with Network connection between cloud desktop example 112.Although health monitor 144 is illustrated as separating using 142 with cloud desktop client , health monitor 144 can apply 142 part alternatively as cloud desktop client.Furthermore health monitor 144 It is shown on user equipment 140.But health monitor can be alternatively positioned in cloud desktop environment 100.But it is strong Health monitor server can reside in cloud desktop environment 100.Furthermore it is real that health monitor can reside in trustship cloud desktop One of server of example or it is multiple on.
In previous example, cloud desktop client application is described.But not necessarily to use cloud desktop client Using.In some embodiments, it can check that cloud desktop example, the browser show the content of cloud desktop in web browser.
Control plane 130 identifies the position in the region where cloud desktop example 112 is run.For example, cloud desktop client application 142 can be connected to cloud desktop through single access point (for example, connection manager (not shown)).Control plane 130 is directed toward server The cloud desktop example 112 run at 110.As a result, when user is connected to the cloud desktop, it is real that control plane 130 is directed toward the cloud desktop Region where example 112.Control plane 130 also contain the information in related other regions that can be attached as a result, if user more Change region (or if this change executes automatically), control plane 130 will be directed toward the cloud desktop example run at new region.Though Right Fig. 1 shows two regions, but the diagram is for illustrative purpose, and there is more multizone.Further more, diagram is every One, a region server, wherein there may be multiple servers in region.In addition, although control plane 130 is illustrated as and cloud table Face server is separated, but it can also be located on one or more servers.
On cloud desktop example server 110 in the zone in trust.Server 110 provides the reality of the cloud desktop of user Example.Server 110 receives from user equipment 140 and inputs and operated to cloud desktop example 112, thus by user equipment 140 On input be construed to the input to cloud desktop example 112.For example, if the cloud table run on user click user equipment 140 Icon in the session of face, the then corresponding application on server 110 will be performed in cloud desktop example 112.Cloud desktop example 112 May include being exemplified to provide a user to computing resource or calculate node, such as the virtual machine of the access right of virtual desktop.It is standby Selection of land can create cloud desktop example 112 without the use of virtual machine on server 110.
Cloud desktop example 112 may include desktop environment.Desktop environment may include any kind of expression virtual desktop Environment.For example, desktop environment may include the interface for being interacted with the file and/or application stored in cloud desktop.One In a little situations, desktop environment may include including or the quick side of the data of trustship and/or application for accessing another example Formula.Furthermore in some cases, desktop environment can be provided for accessing file other than desktop and application additionally or alternatively Interface.For example, desktop environment may include or can be file manager.In some cases, no matter underlying operating system and/ Or hardware, desktop environment can be with presentation specific appearance and feelings.For example, desktop environment can be configured to emulation Windows tables Face, Linux desktops or iOS desktops.In other cases, which can be one of virtual machine computing resource of user's selection Point.In such a case, desktop environment can be the desktop environment (example for the operating system selected for the virtual machine computing resource Such as, Windows, Linux etc.).
In previous example, the individual server 110 for running cloud desktop in this region is described.However, it is possible to recognize Know, multiple servers can be used to cloud desktop.For example, individual server can include the book of the desktop.
It, can be by the book of the cloud desktop of user from previous if user wants never its cloud desktop of same district domain browsing Region moves on to the server 120 at new region, and can start new cloud desktop example 122.
It determines its cloud desktop being moved to another region for example, user can be based on many factors.For example, if user A geographic area (that is, data center's trustship of the geographic area its cloud desktop example) is lived in, but it is different by being in For a period of time, then the user can determine its cloud desktop moving on to new geographic area for geographic area.The position can by for example with The IP address of family equipment determines.Alternatively, cloud desktop application can prompt user (for example, by health monitor 144 or net Network monitor) its network health difference or if its cloud desktop is moved to another region by user, its delay can be improved.This Prompt can occur in cloud desktop session start, occur in certain times of cloud desktop ession for telecommunication, (the example under user instruction Such as, user opens application to test its network speed) or the time occurs at regular intervals in cloud desktop conversation procedure.
In previous example, cloud desktop session is described.It should be understood that the session of cloud desktop can refer to wherein near The connection of one example is redirected to meeting of second example without disconnecting (for example, user logs on in individual session) with user Words.Cloud desktop session can also refer to wherein dismantle to the connection of the first example and start to the second foundation (example of the second example Such as, the instruction that its session is reconnecting can be provided user) session.Cloud desktop session is not limited to be described above, and And the company of the first example from from user equipment to a region and the second example at another region can be that by Any session connect.
Geographic area and delay
Data center is located in a geographic area.For example, single region (for example, Oregon, Portland) can be with trustship Data center (for example, Portland data center).Another region (for example, Florida, Miami) can be different with trustship Data center (for example, data center of Miami).The cloud desktop of user can be hosted in any one of these data centers. The user for being desirably connected to its cloud desktop (that is, cloud desktop example) can be accessed by its user equipment comprising its cloud desktop reality The data center of example.Including the data center of the cloud desktop example of user can be the data for the cloud desktop foundation for being initially user Center.But if user changes position (for example, user wishes to work from Miami), the primary data center of user can Can the cloud desktop session of geographically very remote (for example, cloud desktop is hosted in Portland data center) and/or user may There are high latencies.It may be expectation that cloud desktop, which is navigated to, as a result, and is closer to the data center of user.For example, can calculate User calculating equipment and can determine whether to move cloud table to the network delay of current region using delay threshold value Face.
Furthermore the reason of other than data center is relative to the distance of user equipment, delay may increase.Depending on use Family is being connected to the concrete mode of data center (passing through network), and delay may increase according to connection.For example, if user It attempts to connect to data center and network topology from user equipment to the data center is very long or advance in connection at a slow speed, then Delay will likely be high.The geographic distance reduced as a result, between user equipment and destination data center can improve network delay. But not such was the case with for situation.For example, if data center geographically close to user equipment, but from user equipment to The connection of the data center is slow, then user can be by being connected to geographically farther out but between data center and the user equipment Faster data center is connected to experience better performance.
In some embodiments, it can be not based on network delay, but destination region is selected based on other criterion.Example Such as, if there are regulations and regulation that related data store for a country, mesh can be selected based on these regulations and regulation Ground region.Furthermore if carrying cost is different between data center, user can select purpose based on billing structure Ground region.The selection of geographic area is not limited to above description, and can utilize any amount of because usually determining purpose area Domain.For example, if there is the history delayed data in a geographical location, then destination can be determined based on the history delayed data Region.
Migrate cloud desktop
Fig. 2 is to show migration virtual desktop (for example, cloud desktop or another type of virtual desktop, such as preset virtual table Face) exemplary method flow chart.At 210, the network delay based on user calculating equipment to current region and user's meter At least one of the geographical location of equipment relative to current region is calculated to migrate cloud desktop from current region to determine.Example Such as, user can receive instruction：Network health is poor (for example, high latency or connection reliability).Cloud desktop session as a result, can be with It is recommended that cloud desktop volume is moved on to different zones by user.It can prompt the user with and migrate their cloud desktop, and based on user's Selection can make the determination of migration cloud desktop.When the determination can be happened at the cloud desktop session start of user, user's request When or can be continuously monitored by the state of network.Further, it is also possible to prompt the cloud with the associated administrator mobile subscriber of cloud desktop Desktop (for example, if administrator receives the instruction that network delay is more than threshold value) and administrator can determine cloud desktop Move to different regions.
At 220, network delay and user calculating equipment based on user calculating equipment to destination region relative to At least one of the geographical location in the destination region identifies the destination region for moving to cloud desktop.It can be to user It provides geographically close to the list of the data center of the user.Alternatively, cloud desktop can execute ping to multiple data centers It (the Internet packets survey meter) and is signed using the time of the grouping received to determine destination region.It can be marked by user Know destination region or destination can be automatically determined.For example, once it is determined that cloud desktop should be migrated, then it can be with recognition purpose Ground region is without input from the user.There can be more than one candidate region.Based on such as user equipment to one or more Geographical location of the network delay and user calculating equipment of a candidate region relative to the one or more candidate region, can be with These candidate regions are assessed to determine destination region.
At 230, the instant example (that is, first example) of the cloud desktop run at current region is closed.Because moving Cloud desktop is rolled up, thus in order to ensure during migration the volume be not modified (that is, from user makes change to cloud desktop), can be with Cloud desktop session is suspended.For example, the session can show progress bar or certain other instruction：Cloud desktop is moving or currently It is unavailable.
At 240, the book of cloud desktop is moved on into destination region from current region.Book may include and the cloud The user data of the user-association of desktop, using data, application software, operating system software or by cloud desktop move on to purpose area Any aspect needed for domain.
At 250, start the new example of cloud desktop at the region of destination using mobile book (that is, second is real Example).Second example can according to operation system image, the cloud desktop example of user from current region, movement book And/or the second example for the cloud desktop any other software or setting re-create.
At 260, when receiving user's connection request, the cloud table that user's connection request is directed at the region of destination Second example in face.User can receive the instruction that its cloud desktop has moved or can move cloud desktop without notifying user. In addition, user without know cloud desktop have been moved to where.Indicate its cloud desktop by mobile for example, user can receive Instruction.
Fig. 3 is to show migration virtual desktop (for example, cloud desktop or another type of virtual desktop, such as preset virtual table Face) another exemplary method flow chart.At 310, based on user calculating equipment to the network delay at current data center And at least one of the geographical location of user calculating equipment relative to current data center is determined cloud desktop from working as Preceding data center's migration.It, or can be constantly when user asks when the determination can be happened at the cloud desktop session start of user Monitor the state of network.
At 320, the network delay based on user calculating equipment to destination data center and user calculating equipment phase At least one of geographical location for the destination data center is come will will be in candidate data center that cloud desktop moves to One be identified as destination data center.The row at the geographically candidate data center close to the user can be provided a user Table.Alternatively, cloud desktop can execute ping to multiple candidate data centers, and select user calculating equipment to destination data The network delay at center is less than the user calculating equipment to the data center of the delay at current data center.
At 330, the book of cloud desktop is moved on into destination data center from current data center.At 340, connecing When receiving user's connection request, user's connection request is directed to the example of the cloud desktop run at destination data center.It can Management assembly is used when either step in the step of execution is mentioned above.
Fig. 4 is the computing system schematic diagram of cloud desktop environment 400 and Fig. 5 is the exemplary method for showing migration desktop Flow chart.User can start cloud desktop meeting for example, by the cloud desktop client run on user equipment 440 using 442 Words.User equipment 440 can be connected to the cloud run on the server 410 at a region by cloud desktop client using 442 Desktop example 412.
At 510, determination will migrate cloud desktop from current region.The cloud desktop session that the determination can be happened at user is opened When the beginning, when user asks or the state of network can be continuously monitored by.The determination can be by the health monitoring on user equipment 440 Device 444 executes.Control plane 430 identifies the position in the region where cloud desktop example 412 is run.
At 520, the destination region for moving to cloud desktop is identified.It can provide a user geographically close to the user Data center list.Alternatively, cloud desktop can execute multiple data centers ping and using the grouping received Time sign and determine destination region.
At 530, the book of cloud desktop is copied into destination region from current region.Book may include and use Cloud desktop using data, application software, operating system software or is moved on to any aspect needed for the region of destination by user data. At 540, the cloud desktop at cloud desktop data volume and the destination region at current region is synchronously safeguarded in a replication process Book.For example, if causing book to be modified due to such as new document of user's preservation, it will to the change of the book It is replicated, so that it is guaranteed that the book at the book and destination region at current region appears to be identical.
At 550, when replicate complete when, freeze at current region the associated active user's session of cloud desktop (for example, Active user's session is locked or suspends until being reconnected to new example).Ensure that proparea can not possibly be being worked as in this way Any new change is carried out at domain, so that the book at current region becomes different from the book at the region of destination Step.Although active user's session is freezed in present exemplary description, active user's session is without having to be frozen.For example, can To record the change at current region and transfer upwards, it is until such as user is switched to the example run at the region of destination Only.
At 560, by current region current storage and processor state copy to destination region.At 570, Start second on the server 420 at the region of destination using the book of duplication and current storage and processor state Cloud desktop example 422.The cloud desktop example for enabling the second cloud desktop example 422 to seem and run at current region in this way 412 is substantially identical.For example, what is run at cloud desktop example 412 at current region before replicate data volume any answers With will be run on the second cloud desktop example 422.
At 580, active user's session is reconnected into the second cloud desktop example 422.Because of the cloud at current region The appearance of desktop example and the second cloud desktop example is identical (that is, desktop appearance is identical), so user even can be with Do not know that cloud desktop has been moved to destination region.
In above description, term " movement " and " duplication " are used interchangeably.Due to replicating and/or moving operation The reason of essence, it should be appreciated that copy can be retained on source device, until duplication/moving operation is completed.As ability Known in domain, data retention can be carried out in the case ofs disconnection, service disruption etc. in this way.
